Abstract
For the reproduction of colored originals, a set of standard color patches is scanned with an original to be reproduced and corresponding signals are applied to a display system having controls for adjusting the appearance of the displayed original and color patches. The standard color patch signals applied to the display are gated out and used to adjust a color-modifying means in the signal path between the input scanner and the output scanner, for reproducing the original, in such a manner that the standard color patches if reproduced by the output scanner would simulate the appearance of the displayed standard color patches after the adjustment of the display system.
